Even if Turbo Tax lets you submit your return they will just hold all the returns until the IRS opens filing on Jan 27, 2021 or later. So there is no hurry. And a lot of people who file early find out they have to amend later like when they get their actual W2 and 1099 forms. Or they get more forms than they were expecting or forgot about.
MY RETURN IS IN PENDING—what does that mean?
Did you e-file? Did you click that big orange button that said “Transmit my returns now?” If so, your return is now in “pending” on a server. Do not try to change anything while your return is in pending.
The IRS will not be accepting/rejecting 2020 returns until at least the end of January. You need to watch your emails for the acceptance/rejection notice that may take until the end of the month to arrive in your inbox. And watch your spam folder too.
When you e-file your federal return you will receive two emails from TurboTax. The first one will say that your return was submitted. The second email will tell you if your federal return was accepted or rejected. If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.
A state return cannot be accepted until the federal return has been accepted.
